I have a Gen7 v1.3.1 board that I am trying to get working for the first time. I am having trouble uploading the bootloader. I am using a Polulu USB AVR Programmer (http://www.pololu.com/product/1300) and Windows 8. I am following the instructions here (http://reprap.org/wiki/Gen7_Arduino_IDE_Support#Bootloader_Upload). I have tried this on two different Atmega644 chips and get the same error.by gphysics2014 - Controllers
